Title: Shih-Chii Liu: Innovator in Sensor Technology
Introduction
Shih-Chii Liu is a prominent inventor based in Pasadena, CA, known for her contributions to sensor technology. With a total of 2 patents, she has made significant advancements in the field of image processing and vehicular traffic monitoring systems.
Latest Patents
Liu's latest patents include a nonlinear resistive network for isolating outliers in sensor images and a vehicular traffic monitoring system. The nonlinear resistive network is designed to identify, isolate, and reject outliers in sensor images by utilizing switches in the data paths. During normal operation, images are received with all switches in a closed state. If the data at a given pixel differs from its immediate neighbors by a predetermined threshold voltage, the corresponding switch is opened. This process allows for the generation of a noise-free image and the identification of outlier points in a computer vision system.
The vehicular traffic monitoring system incorporates an array of photosensors and a nonlinear resistive network to identify and process outliers in sensor images of highways or intersections. The camera system can be mounted on poles or overpasses to capture images of the roadway. The system detects the presence of objects by comparing pixel intensity with the background. If a pixel's intensity significantly differs from the background level, its data path switch is opened. This results in a map of outlier points for each video frame, which is connected to a data processing system to identify and locate outlier points in the image.
